Board Technical Description
Silicon Labs Si5368
A Silicon Labs Si5368 any-rate precision clock multiplier/jitter attenuator integrated
circuit provides a wide range of clocking applications for the Xilinx board and XM104
combination. Table 1-13 shows the connections of the SI5368 differential clock outputs to
the XM104 FMC HPC connector. Table 1-13 also shows connections of the clock outputs
from the board to the inputs of the SI5368.
